MAX7376 is a silicon oscillator with reset that replaces ceramic resonators, crystals, crystal oscillator modules, and discrete reset circuits. It provides the primary clock source and reset function for microcontrollers in 3V, 3.3V, and 5V applications. The MAX7376 features a factory-programmed high-speed oscillator and a microprocessor (µP) power-on-reset (POR) supervisor. Unlike typical crystal and ceramic resonator oscillator circuits, the MAX7376 is resistant to vibration and EMI. The high-output-drive current and absence of high-impedance nodes make the oscillator less susceptible to dirty or humid operating conditions. With a wide operating temperature range as standard, the MAX7376 is a good choice for demanding home appliance, industrial, and automotive environments. The MAX7376 is available in factory-programmed frequencies from 32.768kHz to 10MHz. See Table 2 for standard frequencies and contact the factory for custom frequencies. The MAX7376 is available in a 5-pin SOT23 package. Refer to the MAX7382 data sheet for frequencies ≥10MHz. The MAX7376 standard operating temperature range is -40°C to +125°C. See the Applications Information section for the extended operating temperature range.
The MAX7376 is a silicon oscillator with an integrated reset output designed as a replacement for ceramic resonators, crystals, and crystal oscillator modules. It provides a primary clock source and power‑on‑reset supervisor for microcontrollers operating from 2.7 V to 5.5 V, and is suited for home‑appliance, industrial, and automotive environments.
Key features include a factory‑programmed frequency from 32.768 kHz to 10 MHz, +10 mA clock output drive, low jitter (160 ps p‑p at 8 MHz), and a reset output that holds the processor in reset for 100 µs after power‑up. The device is offered in a 5‑pin SOT‑23 package and operates over a temperature range of –40 °C to +125 °C.
